The path difference between two wavefronts
WebbFIGURE 4: A: Optical path length (OPL) for reflected ray is proportional to 2/cosα, with α=α' being the incident angle and S the point of reflection. Any alternative path is longer. For the alternative path shown, via alternative surface point S A, the OPL is, for small angles, proportional to 1+1/cos(2α). B: Optical path length for refracted ray is not the shortest … Webbpath difference=dsin Where, θ is the angle at which they emerge. For constructive interference, the path difference should be an integral number of wavelength, Where λ is the wavelength of the monochromatic light used and n is the integer. When n=0, sin =0 and hence θ=0, and this is called the zero-order maximum.
